Answer:

45 mins

Step-by-step explanation:

The question is how much time should the painter spend on painting a doll for the costs to still be equal or lower to $24.50

We can make this equation, representing the raw materials + the painting job (at $18/h):

$11 + $18x = $24.50

18x = 13.50

x = 13.5 / 18 = 0.75

So, the painter should spend at most 3/4 of an hour (or 45 mins) painting a doll to keep the cost at or below $24.50 per doll.

Write the equation of the circle graphed below.
mojhsa [17]

Answer:

As shown in picture, this circle has radius 1.5 and passes (0, 1.5)

=> According to the general form of equation of circle that has radius r and passes (a, b): (x - a)^2 + (y - b)^2 = r^2, we have:

x^2 + (y - 1.5)^2 = 1.5^2

<=>

x^2 + (y - 1.5)^2 = 2.25

Hope this helps!

Trinh is serving 112 people cake , 5/8ths are getting chocolate how many people will get carrot ?
Novay_Z [31]
Hey! 

If 112 people are getting cake and 5/8 are getting chocolate, that means the remaining will get chocolate.

8/8 - 5/8 = 3/8

3/8 are getting chocolate. You have to find 3/8 of 112.

3/8 × 112 = 336/8 = 42

42 people are getting carrot cake

10. The continuously compounded annual return on a stock is normally distributed with a mean of 20% and standard deviation of 30
ehidna [41]

Answer: We should expect its actual return in any particular year to be between<u> -40%</u> and<u> 80%</u>.

Step-by-step explanation:

Given : The continuously compounded annual return on a stock is normally distributed with a mean 20% and standard deviation of 30%.

From normal z-table, the z-value corresponds to 95.44 confidence is 2.

Therefore , the interval limits for 95.44 confidence level will be :

Lower limit = Mean -2(Standard deviation) = 20% -2(30%)= 20%-60%=-40%

Upper limit =  Mean +2(Standard deviation)=20% +2(30%)= 20%+60%=80%

Hence, we should expect its actual return in any particular year to be between<u> -40%</u> and<u> 80%</u>.

: A sports store sells a total of 70 soccer balls in one month, and collects a total of $2,400. A limited Edition soccer ball is
sweet-ann [11.9K]

Answer:

The store sold 43 pro NSL soccer balls.

The store sold 27 limited Edition soccer balls.

Step-by-step explanation:

Let x represent number of limited Edition soccer balls and y represent the number of pro NSL soccer balls.

We have been given that a sports store sells a total of 70 soccer balls in one month. We can represent this information in an equation as:

x+y=70...(1)

Cost of x limited Edition soccer balls: 65x

Cost of y pro NSL soccer balls: 15x

We are also told that store collected a total of $2,400. We can represent this information in an equation as:

65x+15y=2400...(2)

From equation (1), we will get:

x=70-y

Substituting this value in equation (2), we will get:

65(70-y)+15y=2400

4550-65y+15y=2400

4550-50y=2400

4550-4550-50y=2400-4550

-50y=-2150

\frac{-50y}{-50}=\frac{-2150}{-50}

y=43

Therefore, the store sold 43 pro NSL soccer balls.

Now, we will substitute y=43 in equation (1) to solve for x:

x+43=70

x+43-43=70-43

[tex]x=27/tex]

Therefore, the store sold 27 limited Edition soccer balls.
